Study on Molecular Mechanism for Plant Immune System



Plants have immune system against pathogen infection. In our research group, isolation of disease resistance genes, analysis of signal transduction pathways for disease resistance and characterization of defense-related proteins have been performed so far. In addition, we produced transgenic plants expressing green fluorescent protein under the control of defense-inducible promoter, which will be useful to visualize the induction of defense system.

Targeted Application(s)/Industry

Our knowledge obtained from the study on the mechanism(s) for plant immune system and the reporter transgenic plants will be available for screening chemical compounds activating plant immune system (so-called "plant activator").
